For customers who want to know about their recent trading behaviors, we added a new chart in order book with a line of average cost, points of purchase and points of sales.
1. Average cost line
To have a direct and quick view of your recent average cost of a specific trading pais, instead of exporting the order history and calculate the cost, now you have a more intuitive option - average cost line, which indicates the average cost of all the orders executed after your last liquidation.
Average cost = (Total value of all purchases - Total value of all sales)/(Total quantity of all purchases - Total quantity of all sales)*
*The current average cost of a specific trading pair will be calculated from the moment of execution of a new order after your last liquidation of the base coin (liquidation means a balance of the base coin less than R$ 10).
For example, your BTC balance is R$ 9,88 on April 20th and you placed 4 orders of purchase and 3 orders of sales of BTC/BRL. The average cost will be calculated based on these 7 orders.
Once your BTC balance drops again below R$ 10, the average cost line will be erased.
The line will not be shown when the average cost is not covered by the price range of the chart.
2. Point of purchase and point of sales
In the same chart, you can see the points which mark your executed orders (purchase and sales) during the past 48 hours. A point of purchase is marked as a green B and a point of sales is marked as a red S. The points are marked based on the execution time of the order.
